Researchers from the University of Cambridge found that testosterone can actually affect the productivity of male traders in the financial sectors. They studied 17 London male traders for eight straight days. Their hormonal levels were measured by obtaining saliva samples twice in a day. The first sample was taken in the morning, while the last sample was taken in the afternoon. Traders also recorder their profit and loss during sample time.

During the course of the study, scientists observed a pattern where testosterone levels were significantly higher during times when traders make more profits. In fact, they even make more than a month of their daily average. However, excessive testosterone levels can also lead to risk-taking, which could lead to traders to unprofitable levels. There were previous studies conducted that showed how testosterone excess could lead to irrational decision-making. Furthermore, a higher testosterone level can also cause impulsiveness and sensation seeking. In extreme cases, euphoria and mania can be experienced.

In conclusion, Professor Joe Herbert of Cambridge Center for Brain Repair said that hormones play an important role in decision-making. Hormones may also play a vital role in the performance of an individual trader. They tend to be surrounded by stress and pressure in their work. They also have to make rapid decisions. Therefore, any decisions made in the financial world should always take hormones into account.
